Cookie Policy
Last updated 28 September 2026
Prow uses only cookies and browser storage that are needed to run the app you asked for: keeping you signed in, keeping your trading keys on your device, remembering your settings and making the app work offline. We do not use advertising, analytics or tracking cookies.
1.What these are
Cookies are small files a website stores in your browser. Local storage, IndexedDB and Cache Storage are similar browser features that keep data on your device. This policy covers all of them, and explains the rest of what we do with data in the Privacy Policy.
2.Set by Prow
All of these are strictly necessary for the service or store a preference you set. Apart from the prow_tos cookie, none of them is sent to our servers.
| Name | Type | Purpose | Duration |
|---|---|---|---|
| prow_tos | Cookie (HTTP-only) | Remembers that you accepted the current Terms on this device, so trading screens open without asking again. | 1 year, or until the Terms change |
| prow-keys (IndexedDB) | IndexedDB | Your trading keys, encrypted with a key that cannot be exported from the browser. Needed to place and cancel orders. | Until you remove the key, sign out with key removal, or clear site data |
| prow-theme | Local storage | Light, dark or system theme. | Until cleared |
| prow-cookie-notice | Local storage | Remembers that you closed the cookie notice. | Until cleared |
| prow-chart | Local storage | Chart timeframe, style and indicators. | Until cleared |
| prow-markets | Local storage | Favourite markets, last tab, recent searches, rows per page. | Until cleared |
| prow-venue-selection | Local storage | Which connected venue account is selected. | Cleared on sign-out |
| prow-cctp-deposits | Local storage | Tracks USDC deposits in progress so you can follow them after a reload. | Cleared on sign-out |
| prow-sidebar-trade-expanded | Local storage | Whether the Trade section of the sidebar is expanded. | Until cleared |
| Service worker and Cache Storage | Cache Storage | Stores app files (scripts, styles, images, the offline page) so Prow loads fast, installs as an app and shows a page when offline. Account data is never cached. | Replaced on each app update |
3.Set by services we use
These are set by the sign-in and wallet providers built into Prow, only when you use sign-in or connect a wallet.
| Name | Type | Purpose | Duration |
|---|---|---|---|
| Privy (privy:* keys; privy-token, privy-refresh-token, privy-id-token, privy-session cookies depending on configuration) | Local storage, cookies | Keeps you signed in and secures your session. | Session tokens expire and refresh; removed on sign-out |
| Wallet connections (wagmi.*, wc@2:*, WalletConnect / Reown and Coinbase Wallet keys) | Local storage, IndexedDB | Remembers the wallet you connected and the encrypted WalletConnect session with it. | Until you disconnect the wallet or clear site data |
| Cloudflare Turnstile (loaded by Privy during sign-in) | Cookies on Cloudflare's domain | Bot protection for sign-in. | Short-lived |
4.Why we show a notice, not a consent prompt
Because everything listed here is strictly necessary to provide the service you request, or stores a choice you made, we do not ask for cookie consent. A short notice at the bottom of the screen tells you this and links here; closing it only hides it on this device. If we ever add analytics or any other non-essential cookie, we will ask for your consent before setting it and update this page.
5.Your choices
- Signing out clears your session, venue selection and pending deposits, and can remove trading keys from the device.
- You can delete everything by clearing this site's data in your browser settings. You will need to sign in again and create a new trading key; your funds and positions on the venue are not affected.
- Blocking these cookies or storage will stop sign-in or trading from working.
